Echinococcosis granulosus/hydatidosis an endemic zoonotic disease in Egypt.

The hydatidosis patients were collected from Mansoura University's Hospitals and Dakahlia Public Health Hospitals. The patients were divided into three groups: GI: 74 patients with surgically confirmed cystic echinococcosis (CE), GII: 45 patients with other parasitic infections, GIII: 30 healthy parasite-free individuals. All were subjected to questionnaire and full clinical examination, imaging investigation, routine laboratory examination, and serum samples for antibody against CE by the specific ELISA. The hydatidosis was higher in females but without statistically significant difference (p = 0.309). There was no age predilection difference regarding hydatidosis infection. However, the hydatidosis granulosus was significantly higher in the shepherd followed by the farmers. All the questionnaires were positively correlated to hydatidosis infection except the availability of clean domestic water and personal knowledge about hydatidosis gave negative correlations. The ELISA-OD correlated positively with the imaging investigation (mainly U S stage). The sensitivity of ELISA was 86.7% and specificity was 81.4%. The results were evaluated regarding the local and regional data on echinococcosis/hydatidosis.
